The bus judders to a halt, and Emilia's eyes flutter open against the roughness of Sofia's shoulder. She blinks, registering the slumped weight of her own body, the warmth of Sofia's arm where it's curled around her. The bus is nearly empty—just the driver and a woman with a grocery bag two seats ahead.
"We're here," Emilia says. Her voice is gravelly with sleep.
Sofia shifts, straightening. "The stop before ours."
"Mhm." Emilia stands, the backpack tugging at her shoulder. Pebbles shifts inside, a soft rustle of feathers and a single sleepy quack. She pats the bag gently. "Shh. Almost home."
They step off the bus into the gray evening light. The street is quiet, the houses lining it familiar in the way of a route walked twice a day. Emilia's legs feel loose, heavy from the nap, and she lets Sofia take the lead up the front steps.
The key turns in the lock with a click that sounds louder than it should. Inside, the apartment is still—no light under Hazel and Ivy's door, no sound from the kitchen. Just the tick of the wall clock and the hum of the refrigerator. The air smells like lavender and something warm, like the memory of breakfast.
"Your room or mine?" Sofia asks, her voice low.
"Ours," Emilia says, and the word feels new in her mouth.
Sofia's lips twitch. She walks past the closed door of Hazel and Ivy's room, past the bathroom, and pushes open the door to the room they share.
The curtain is half-drawn, the light inside soft and amber from the streetlamp outside. The beds are unmade, their sheets tangled from the morning's rush, and on the pillow lies a small rectangle of white plastic. Unopened. A balloon, still in its packaging, waiting.
Emilia sets the backpack down by the dresser. Pebbles is already asleep again—she can feel the slow rise and fall of his small body through the fabric. She crosses to the edge of the mattress and sits, the springs creaking softly.
Sofia picks up the package. Her thumb runs along the edge, feeling the heat-sealed plastic, the slight give where the balloon rests inside. "I haven't opened it yet," she says, her voice low. "I wanted you to be here."
The plastic crinkles as she brings it closer, her fingers finding the notch at the top where the seal begins.
Emilia watches her hands. The careful, deliberate way Sofia opens things—not tearing, but splitting the seal along its seam, her thumb pressing in with a precision that suggests she's been thinking about this moment all day. The package parts, and she pulls out the deflated balloon.
It's red. A deep, matte red, almost the color of dried blood in this light. Sofia holds it between both palms, the latex flat and cool, and she doesn't say anything.
"Can I?" Emilia asks.
Sofia passes it to her.
The texture is familiar now—the slight tackiness, the powdery residue of cornstarch. Emilia presses it between her fingers, feeling the give, the way it clings to itself. She holds it to her nose and breathes in: rubber, plastic, something clean and chemical that makes her shoulders drop.
"I thought about it all day," Sofia says. She's sitting cross-legged on the bed now, her hands in her lap, her eyes on the balloon. "In class. On the bus. Every time Ms. Patel said my name, I was thinking about this."
Emilia looks up. "What were you thinking?"
Sofia's jaw works. She picks at a thread on her knee. "That I wanted to hear it. The sound. But I also wanted—" She stops, her throat bobbing. "I wanted to feel it first. Before it goes."
The word goes hangs between them. Not pops. Goes.
Emilia nods. She knows the difference now. She can feel it in her own body—the need to hold, to press, to keep the shape intact before the air is even inside it. She lays the balloon flat on her palm and looks at Sofia.
"Together?"
Sofia's voice drops. "Yeah."
They move without speaking. Emilia finds the neck of the balloon, pinching it open with her thumb and forefinger, and brings it to her mouth. The latex presses against her lips, and she breathes in, slow, feeling the chamber fill, the material tighten against her cheeks. She breathes again, harder, and the balloon swells, a soft hiss of air as the red begins to take shape.
Sofia watches. Her breath goes still.
Emilia pulls the neck away, pinching it shut, and holds the inflated balloon between them. It's swollen, round, the surface glossy in the dim light. A perfect sphere of red, like a heart that hasn't learned to beat yet.
Sofia reaches out and touches it. Her fingers trace the curve, the tension, the way the light bends at the edges. She presses her palm flat against it, and the balloon yields, soft and tight at once.
"I want to feel it," she says. "Against my skin."
Emilia's pulse quickens. She keeps her voice steady. "Then let's."
They undress in the half-dark, folding clothes onto the chair, their movements unhurried. Emilia's glasses fog as she pulls her sweater over her head, and she takes them off, setting them on the nightstand. The room blurs at the edges, softened into watercolor, but Sofia's shape is clear—her shoulders, the curve of her spine, the way she turns to face the bed.
The balloon lies between them on the mattress. Sofia lies down first, on her back, her hair fanned across the pillow. She pulls the balloon onto her chest, holding it there with both hands, its red surface a stark contrast against her skin.
Emilia lies beside her, propped on an elbow. She doesn't touch yet. She watches.
Sofia closes her eyes. She presses the balloon against her sternum, feeling the cool give of the latex against her skin, the slight resistance as she pushes. Her breath comes slow, measured. She rolls the balloon down her stomach, over the soft curve of her belly, stopping at the crest of her hip.
"It's different," she whispers. "When I know it's not going to—" She stops. "When I know you'll catch it."
Emilia's throat tightens. "I will."
Sofia opens her eyes. The amber light catches the wet rim of her lashes. "Show me."
Emilia reaches for the balloon. Her hand finds Sofia's, and she guides it, pressing the red sphere between them, against Sofia's chest, against her own. The latex is warm now, carrying the heat of two bodies, and the pressure is perfect—not too much, not too little. Just the weight of air and latex and two girls holding it together.
Sofia's breath catches. A small sound, almost a whimper, her mouth falling open as she pushes into the balloon, seeking more pressure, more contact. Her body shifts, and the balloon rolls between them, and she makes a noise that is barely human.
"Like that," she breathes. "Don't stop."
Emilia doesn't. She holds the balloon steady, presses deeper, feels the latex stretch against both their bodies. The heat is building—between her thighs, in her stomach, behind her eyes. She wants to see Sofia's face, but she can't look away from where their hands meet, cradling the red sphere like something sacred.
The balloon creaks, a tiny sound of latex straining.
Sofia's hand clenches. "Not yet."
"I know."
They breathe together. The balloon pulses between them, the air inside warming, the latex softening. Emilia shifts, and the balloon slides down, settling between Sofia's legs, pressing against the place where she's already starting to slick.
Sofia gasps. Her hips rise, pressing back, and the balloon molds against her, the friction a dull, perfect ache. She rocks against it, a slow, grinding motion, her hand still holding it in place.
"Tell me," Emilia says. "When you want it to go."
Sofia's eyes are closed again, her jaw slack, her breath coming in shallow pulses. She rocks again, harder, the latex squeaking against her skin. "Not yet. Not—" Her voice breaks. "I want to feel it first. All of it."
Emilia watches. She doesn't take her hand off the balloon. She feels the vibration of Sofia's body through the latex, the tremble in her thighs, the way the pressure shifts as she moves. It's the most honest thing she's ever seen.
"Okay," she says. "I'm here."
Sofia's hand finds hers on the balloon. She doesn't open her eyes. She just holds on, rocking, pressing, her breath turning into a low, broken sound that might be a sob.
The balloon holds. The red sphere keeps its shape, swelling and yielding as Sofia grinds against it, as Emilia's hand stays steady. The room is silent except for the creak of the bed and the wet sound of Sofia's movement and the soft, rhythmic sigh of latex against skin.
Time doesn't pass. It just is. This moment, this balloon, this girl beneath her hand.
Sofia's rhythm changes—faster now, her hips moving in an arc, her breath turning to gasps. Her hand tightens on Emilia's, hard enough to bruise.
"I'm—" She doesn't finish. Her body arches, her back bowing off the mattress, and the balloon presses deeper, catching her weight, catching the surge of her climax as she shakes through it, a long, shuddering breath that ends in a whimper.
Emilia holds the balloon steady. She feels the aftershocks ripple through Sofia's body, felt through the latex, felt through the air between them.
Sofia lies still, her chest heaving. Her hand is still clamped around Emilia's.
"Fuck," she whispers. "Emilia."
"Yeah."
Sofia opens her eyes. They're wet, and her face is flushed, and she looks raw in a way that makes Emilia's chest ache. She looks at the balloon, still pressed between them, still whole, and her mouth trembles.
"I didn't—" She stops. "I thought it would feel different. With you watching."
"How does it feel?"
Sofia's voice cracks. "Like I'm not alone."
Emilia leans down and presses her lips to Sofia's forehead. "You're not."
The balloon sits between them, red and round and unbroken, a promise still held. Sofia's hand is warm in hers, and the latex is cooling, and somewhere down the hall, Ivy and Hazel are making dinner, and the evening is still young.
Emilia doesn't move. She stays, her hand on the balloon, her body curved around Sofia's, and she holds the moment, not because she knows what comes next, but because she wants to feel the shape of it while it's still here.
